The most extensive research, however, was conducted by an Israeli scientist, Dr. Madeleine Mumcuoglu, (pronounced mum-shu-glu) at the Hadassah University Medical Center in Jerusalem.Specializing in immunology and hematology, Dr. Mumcuoglu initiated her work on elderberry in 1992.She
was able to isolate the constituents of the berry that made it so effective against the flu and developed her
own elderberry extract which she
called Sambucol.The Israeli flu epidemic of 1992-1993 gave her
the opportunity to test her
research with a double blind study of flu patients. Her
test patients were divided into two groups.One group
was given four tablespoons of the elderberry syrup per day and the second group was given a placebo.
elderberry syrup effective against Beijing, Singapore, Hong Kong, Ann Arbor, Texas, Panama, Yamajata, and Shangdong (flu viruses).To date, her
extract has been used by over 150,000 people in Israel.
